Is this a good engine for the price

We have used MANY smallblocks from cup shops,,,most notably Roush/Yates engine shop,,we generally paid around 38k for good smallblocks, basically 358cid, they would dyno at 780+hp and didnt run until they turned 8700rpm,,,and would turn those rpms all day long,,,,so its doubtful what this guy is claiming to be a 500 hp motor,,with a 30 to 40 k motor cost is true. Even Clemens house of power in S. Carolina isnt that pricey for a 500hp mopar sb...... just my two cents

The $40,000 plus is in Canadian dollars cost us twice as much to build here. I was thinking about those engines for my cuda. I think there legit. Up here our stock car are pretty old school. Ask about the engine history like which car team it was run in. Might have do a cam change to make it more street friendly. And the dry slump might make installation hard.
